A detective with the Mercer County Sheriff's Department was called to Beulah High School on Friday to investigate a report of a teacher who had been sending nude photos via Snapchat to male high school students, according to an affidavit.

The detective interviewed a 17-year-old male student who made a comment "that he could get the math teacher in trouble for pictures that she had sent him," the affidavit said.

The student told the detective he received three or four naked photos on Snapchat from Schmidt in August and September. The student described the photos were of Schmidt from the waist up with her hair somewhat covering her breasts. Another was a photo of a person's legs with the message, "Get a group and play naked hide and seek."

Schmidt allegedly admitted to the detective that she had sent the nude photos of herself to the student.

Beulah Public School District Superintendent Travis Jordan said Schmidt has been placed on administrative leave, and that the school district is conducting its own investigation.

Jordan said Schmidt is in her first year of teaching at the high school. He declined to comment on whether multiple students were involved, due to the district's ongoing investigation.

Tom Dickson, Schmidt's attorney, said: "This is a very unfortunate situation for everyone, but certainly it's a very serious allegation and we are treating it very seriously."

At Schmidt's initial appearance on Tuesday, South Central District Judge David Reich set her bond at 10 percent of $10,000, court records show. Her preliminary hearing is scheduled for Feb. 27.
